The nanotechnology application areas discussed (bulk materials, functional surfaces, composites, fire and safety, energy, water, electronics and computing, metrology and sensors) will have a significant impact on construction within the next 10-15 years. The areas and products where nanotechnology is expected to have the maximum impact were identified as: Composites, Coatings, Concrete, Energy and Sensors, and Metrology. Products in these nanotechnology disciplines are identified to have the biggest impact on construction. (RR251-11, p. 41)
